Hmmm, what about The Clone Wars? Will Cartoon Network keep the rights to air it?
No reason why not, unless Disney chooses to buy out Cartoon Network's licensing contract. It's hardly unprecedented for a show owned by one corporation to air on a network owned by another -- for instance, Warner Bros.'s Fringe
airing on FOX. There are advantages to having your own corporation's show on your own corporation's network, but it's certainly not mandatory.
Bob Iger mentioned that he likes Star Wars as a TV property and that DisneyXD is a good place for it, so he's taking about the whole idea of kid-friendly animation. They might let The Clone Wars finish its run on the Cartoon Network and then launch a new series on DisneyXD. They might just have animated series run indefinitely, covering different time periods as an adjunct to the movie series.
